OWEN LAUGHLIN, 0F MOUNT STERLING, KENTUCKY.

FILTER.

To all whom it may concern Be it known that I(i OWEN LAUGHLIN, a.

citizen of the Unite States, residing at Mount Sterling, in the county of Montgomery and State of Kentucky, have invented certain new and useful Improvements in Filters, of'which the following is a specification.

This invention rolates to improvements in filters, especially of that class adapted for use in connection with cisterns, and has for its particular object, to provide such a device that is simple in construction, inexpensive to manufacture, and complete in its entirety. I, Y 7

Another object is to provide. a filter that will drain itself and at the same time filter the drainings.

\Vith the above and other objects in View, the presentinvention consists in the combination and arrangements of the parts as will be more fully described hereinafter shown in the accompanying drawings, an particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size and minor details may be made within the scope oftlie claims without departing from the spirit or sacri ficing any of the advantages of the invent-ion.

In the accompanying drawingsf Figure 1 is a vertical sectional view through the device. Fig. 2 is a horizontal sectional View taken above theupper filtering receptacle. part of the same being broken away to show the lower filteringreceptacle. Fig. 3 is a detailed perspective view of one of the removable filtering chambers.

Similar reference numerals in all of the figures of the drawings designate like parts.

Referring to the drawings, 4 designates the body or outer casing, which may be of any suitable form and material. As shown said case is somewhat conical, is provided at its upper end with an enlarged ortion 5, a conical bottom 6, and a remova 1e cover 7. Aninlet pipe 8 connects with the lower end 0f sa1d casing and .is extended upward from said connection and is adapted to be coupled to a supply pipe which may be the downspout of a building. An outlet pipe 9 is connected to said casing at two omts by extenslons 10 and 11, one connection being ad] acent the top of said casing and the other Specification of Letters Patent.

near the bottom. Intermediate the two outlet connections is positioned a removable filtering receptacle comprising preferably a Wire basket 12, preferably of coarse mesh, having a removable wire mesh cover 13. Said basket is filled with suitable filtering material, such as charcoal, coke or gravel 'and the same is confined therein by the cover 13. The said basket 12 preferably fits snugly the sides of the outer casing below the enlarged portion 5, is supported therein by a removable stand 14, the legs of which rest upon the bottom 6, is provided with side handles 15 at its upper edge, and is locked in position by a cross-bar 16, which passes through the handle 16 of the cover 13, and having hooks 17 at its ends which are engaged by the pivoted loops 18 secured to the.

casing. This locking means not only locks the filtering receptacle in position but also.

looks the cover 13 in place upon the filtering material within said receptacle.

'In the chamber 19 formed beneath the filtering receptacle just described, is located an additional filterin same being preferab y frusto-conieal in shape, having a flat bottom side 21, and a receptacle 20, ,the

tubular extension 22, forming a receptacle having a wide mouth and sides sloplng to the extension 22. vided with a permanently fixed perforated diaphragm 23 at theiintersection' of the extension 22 and therecept acle proper, and a hinged perforated or mesh cover. 24, of a finer mesh than of the basket 12,- -a.t its mouth, between which and the diaphragm is confined suitable filtering material. hinged cover 24 is provided with a catch 25 to retain it in a closed position. To prevent said rece tacle 20 from being-displaced and to hold lt' securely in position, a l opklng Said receptacle is pre The means is provided, the same comprising apivoted frame havin side arms 26, the ends of'which are formedinto hooks 27, which engage eyelets 27 on the receptacle 20, and a central extension 28 adapted to be contacted by the bottom of the basket receptacle to force the arms 26 toward the side of the casing and thus press the extension 22 within the extension -11 of'the outlet pipe. Thus it will be seen that when the filtermg receptacles arc in position, the basket filter effectually locks the outlet filter in position, and as said basket filter is locked in its position,

20 removab e cap or cover 33.

and the filtering materials locked in bothreceptacles, the device can be moved bodily, fully, charged for operation, without the danger of disturbing or disarranging its contents. Y

The opening to the extension 10 of the outlet pipe 9 is provided-with a screen '29, the same having a handle '30 and supported in guideways 31', whereby it can be removed when desired. This screen is preferabl "of a smaller mesh than that used for the fi ter-' ing receptacles and is to prevent any fibrous material that may he accidentally in the upper portion of the filter, from passing inMLthe outlet .pipe.

(By forming the bottom 6 conical, or sloping from the center, all sediment will gradually workitself toward the lower or outer edge thereof, and can be drawn through the cleansin opening 32, which is fitted with a In operation, the water from the inlet ,pipe'fiows into the lower chamber 19, flood- 1ng said chamber, and passes through both filtering rece tacles and into the outlet pipe '9 by way of oth extensions 10 and 11, and

as the sediment and trash admitted with the water gradually throttles the lower filter, the greatest amount of water naturall is forced :upward through the upper and larger filtering receptacle. After the supply is lessened or stopped, the water remaining fi gefore reaching the filtering material, the

lower filter will drain itself, its bottom being inclined, and that there are no permanently secured pipes within the casing, thus facilitating the cleaning of the device.

Having thus fully described the invention, what is claimed 1. Afilter, comprising a casing, an inlet 'pipe connected to the lower end of saidcasmg, an outlet pipe having two extensions t connected to said casing, and two removable filtering receptacles positioned withinsaid.

casing between said extensions, one of said filterlng receptacles being adapted to be seated in one of said extensions, and a locking means for retaining said receptacle in saldextension, embodying a pivoted frame having side arms with terminal hooks and a central extension adapted tobe engaged by the other receptacle.

'2. A filter comprising a "casing, an inlet pipe connected to the lower end of said casing, an outlet pipe having two extensions connected to said casing, and two removable filtering receptacles positioned within said casing between said extensions, one of said filtering receptacles being adapted to be seated in one of'said extensions, and a lockmg means for retaining said receptacle in said extensional 1d adapted to be engaged by the other receptacle.

3. A filter, comprising'a casing, an inlet pipe connected to the lower end of said casing, an .outlet pipe having two extensions connected to said casing, a removable receptacle for containing filtering material for one of said extensions, a second removable receptacle for containing filtering material having a removable cover, positioned be tween the two extensions, a removable stand for supporting said second receptacle, and a fastening means for locking said cover and second receptacle in position.

In testimony whereof I aflix my signature in presence of two witnesses.
